“We live in a world in which the common denominator that binds the human family together has been reduced to its simplest fundamental term—human survival.”

Context: I believe in progress; I believe that happiness is the goal of humanity, and I cherish a higher idea of the Divine Being than those pious folk who suppose that man was created only to suffer. Even here on earth I would strive, through the blessings of free political and industrial institutions, to bring about that reign of felicity which, in the opinion of the pious, is to be postponed till heaven is reached after the day of Judgment. The one expectation is perhaps as vain as the other; there may be no resurrection of humanity either in a political or in a religious sense. Mankind, it may be, is doomed to eternal misery; the nations are perhaps under a perpetual curse, condemned to be trodden under foot by despots, to be made the instruments of their accomplices and the laughing-stocks of their menials. Yet, though all this be the case, it will be the duty even of those who regard Christianity as an error still to uphold it; and men must journey barefoot through Europe, wearing monks' cowls, preaching the doctrine of renunciation and the vanity of all earthly possessions, holding up before the gaze of a scourged and despised humanity the consoling Cross, and promising, after death, all the glories of heaven.
The duration of religions has always been dependent on human need for them. Christianity has been a blessing for suffering humanity during eighteen centuries; it has been providential, divine, holy. All that it has done in the interest of civilisation, curbing the strong and strengthening the weak, binding together the nations through a common sympathy and a common tongue, and all else that its apologists have urged in its praise all this is as nothing compared with that great consolation it has bestowed on man. Eternal praise is due to the symbol of that suffering God, the Saviour with the crown of thorns, the crucified Christ, whose blood was as a healing balm that flowed into the wounds of humanity. The poet especially must acknowledge with reverence the terrible sublimity of this symbol.

Context: Both security and development ultimately depend on respect for human rights and the rule of law.
— Although increasingly interdependent, our world continues to be divided — not only by economic differences, but also by religion and culture. That is not in itself a problem. Throughout history, human life has been enriched by diversity, and different communities have learnt from each other. But, if our different communities are to live together in peace we must stress also what unites us: our common humanity, and our shared belief that human dignity and rights should be protected by law.

Context: The thing we must do intensely is be human together. People are more important than things. We must get together. The best thing humans can have going for them is each other. We have each other. We must reject everything which humiliates us. Humans are not objects of consumption. We must develop an absolute priority of humans ahead of profit — any humans ahead of any profit. Then we will survive. … Together.
